mam. I (01. 158-46 This invention relates to -mou'ntiri'gs for oilburners and more particularly to an improved housing foi"-oilbur'nerunits fordomestic heating and the'like. V

It is the principal object of the-pr'es'ent' i'nvention toprovideiinproved mountings for oil burners which will be simple inconstruction, and which willpermit of adjustment of the oil burner head,as well asren'ewal of the same, in'--a-'-simpleand e'ifiediti'ousmanner.

It is a further object of the'prese'nt invention to provide in apparatusof the character aforesaid, a closed chamber'in which parts areaccessible for an adjustment *of the oil burner headl Other objects and--advanta'geous features -of the invention will beapparent' from thespeci-fication-and claim.

The nature and characteristic features of the invention will be morereadily understood from the f following description, taken in connectionwith the accompanying drawings forming part hereof, in which:

Figure 1 is a top plan view of an oil burner in accordance with thepresent invention, parts being broken away to show the details ofconstruction;

Fig. 2 is a fragmentary side elevational view of the burner shown inFig. 1, parts also being broken away to show the details ofconstruction;

Fig. 3 is a fragmentary sectional view taken approximately on the line3-3 of Fig. 2;

Fig. 4 is a fragmentary view showing certain of the details ofconstruction;

Fig. 5 is a view in elevation of the structure shown in Fig. 4; and

Fig. 6 is a fragmentary view of a portion of the structure shown in Fig.2.

It should, of course, be understood that the description and drawingsherein are illustrative merely, and that various modifications andchanges may be made in the structure disclosed without departing fromthe spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the drawings a fan housing It! isprovided, with a spiral or eccentric outer wall H and side walls l2 and13. The fan housing In functions as a collector or scroll, and on oneside thereof an inlet housing section 14 is provided, with inletopenings l5, and on the other side thereof a fan motor 16 is mounted foroperating the fan rotor (not shown) in the housing I0.

"Thesvanese28are-iadaptedstot'slidably support" aburner headitfl, iwhichiiniayrirbeofiiany preferred type. One suitable burner head is that known in thtrade as the Shell head and this is shown in the patent to Glendenning,No. 2,393,897.

The burner head 30 has, extending rearwardly therefrom, the usualignition electrodes 3! and a fuel supply pipe 32 for supplying fuel foratomization, and has a sleeve 33 adjustable by manually turning the samefor determining the quantity of air admitted to the interior of thehead.

Within the interior of the casing section 20, a wall 35 is provided,spaced forwardly from the rear ends of the walls 19, 20, 2|, and 22, andpreferably adjacent the junction of the rear portion of the wall II andthe wall 22. The wall 35 preferably has a central circular opening 36therethrough and the remaining portions of the wall 35 provide abutmentsfor engagement by a closure plate 31. The closure plate 31 by reason ofits shape, complemental to that of the interior of the casing section20, does not turn within the casing section 20.

The closure plate 31 preferably has a bracket 38 thereon, with which abolt 39, insertible through the top wall I9, is adapted to engage forclamping the plate 31 in position and in engagement with the abutmentsprovided by the wall 35. The plate 3! has a central opening 40 withinwhich an adjusting sleeve 4! is mounted. The sleeve 4| is internallythreaded for engagement with threads 42 provided on the rear portion ofthe fuel pipe 32 and has an operating portion 43 with a knurled end formanual engagement. At the rear end of the pipe 32, a fitting 44 isprovided into which the fuel supply pipe 45 from the fuel pump (notshown) is connected for the delivery of the fuel. The fuel supply pipe45 preferably passes through a slot 45 in the rear portion of the sidewall 20, the front terminal of the slot being located rearwardly of theabutment wall 35.

At the rear end of the casing section 20, an end cover plate 41 isprovided, preferably having a bracket 48 thereon, in which a bolt 49,extending through the wall 19 is adapted to engage, for drawing thecover plate 41 to closure position and holding the same.

A chamber 50 is thus provided between the closure plate 31 and the endcover plate 41 within which, upon removal of the cover plate 41,suitable forward and rearward adjustment of the burner head 30 may beeffected.

Each of the side walls 20 and 21 is provided with a rectangular openingin communication with the compartment 25. At one of the openings, acover plate 5| may be secured, by screws 52, in closing relation and, atthe other, a closed control housing 53 may be secured in a similarmanner, and within which the connections (not shown) to the electrodes3i are provided.

The mode of operation will, it is thought, be clear from the foregoing.

It may be noted that by the provision of the rear chamber 50 within thehousing i8 and with the removable cover plate 41, access may readily behad to the adjusting sleeve M for positioning the burner head 30, asdesired, to obtain the best combustion conditions. At the same time theadjusting sleeve 4| is normally enclosed so that 3| may be withdrawn forinspection or replacement. 7

The oil burner assembly may be employed in the position illustrated butmay also, if desired, be turned with the fan housing 10 above the casing20.

I claim:

In an oil burner having an air blast tube and a burner head axiallymovable within said tube and having a rearwardly extending fuel supplypipe for axial movement of said head, the combination comprising acasing having spaced side walls enclosing an interior compartment and atthe front end of which said blast tube is supported in communicationtherewith, means for supplying air under pressure to the interior ofsaid compartment, abutments in the rear portion of said casing spacedfrom the rear end, a removable closure plate for engagement with saidabutments for providing with said casing a separate rear chamher, abracket on said closure plate, a bolt extending through a wall of saidcasing for engagement with said bracket, adjusting means carried by saidclosure plate for axially moving said fuel supply pipe, and a removablecover plate for the rear end of said rear chamber.
